Attacking the edges with pressure was a priority for Tennessee vs. Denver.

Titans running a CB pressure vs. the Broncos.

With the RB to him, the CB needs to take a more vertical angle to counter any pull from the QB.

RB to me = Contain
RB away = Bend to the back

Teaching the Vision Safety: Marrying Saleh’s Quarters and the Weak-Rotations A look at the 49ers' 2025 defense. Learn about Saleh’s Vision Safety, Quarters coverage, and the personnel requirements for the Wide-9 system.

I took a deep dive into the 2025 49ers tape and the "Vision" Safety mechanics at MatchQuarters.

The data shows a unit in flux.

After Week 6, the 49ers slashed split-field usage by 15%, moving to a closed-post mentality to survive.

Still, the "Vision" Safety is elite when the front four eats.

When they don't, it can be schematic hell.

One key adjustment Saleh used to handle 3x1 sets is the "Shove" call.

When a TE chips or a formation condenses, the Weak Safety "shoves" the coverage to the passing strength.

This frees the Field Safety to bracket #1, knowing the backside Safety is the backstop.

The "Passive Pressure" of coverage disguise only works if the QB is forced accelerate his reads.

In 2025, the 49ers hit a personnel cliff.

No Bosa. No Warner.

Without an "Intermediate Eraser" or a pass rush, the Sack Rate in Quarters plummeted to 2.1%β€”bottom in the league.

Robert Saleh’s system relies on the Weak Safety playing "Vision."

By anchoring on the hash, the Safety denies the post-snap "key" modern QBs crave.

The "Vision" mechanic allows the defense to seamlessly shift between Quarters and weak-rotation Cover 3.

The 49ers’ 2025 defensive collapse wasn't a failure of scheme, but a failure of physics.

When the pass rush died, the "Vision" Safety became a spectator.

Here is why the marriage of Quarters and Cover 3 fractured in San Francisco.

How Vic Fangio’s "Trix" Coverage Breaks Modern Offenses

Cover 8 (TRIX) is a foundational scheme in the Fangio structure that muddies post-snap reads by mimicking weak-rotation Cover 3.

I broke it down in this week's Friday Clinic.

Bengals running an Odd Mug "Mex" pressure vs. the Patriots.

DE to the left can break the pocket because the LB is "Hug" rushing the RB.

The play is no different from a Boss (Load) "Not" stunt, which is also very popular.

Same path... Different presentation.

Felix & I talked about the "death" of the Pete Carroll defensive system in the NFL.

No, it's not "dead," it's being recalibrated...
